Title: HOWTO: Prevent editing of TTreeNode
Post by: Marion on May 05, 2021, 10:24:58 pm

I am using the TTreeView but I don't want users to be able to edit the node text. How do I prevent that?

There is also a more direct ReadOnly property; it definitely works, I used it many times.

In case that you only want to inhibit editing of specific nodes you can hook into the OnEditing event which offers a var parameter "AllowEdit" which you simply must set to false in the event handler for the corresponding node.
